RAIL-JOINT.

Specification of Letters Patent.

Patented March 12, 1907.

Application filed August so, 1906. Serial No. 332,573.

f'county, Pennsylvania, have invented anew and useful Rail-Joint, of which the following is a'full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whic Figures, 1 to 18, inclusive, are end views, with one of the rails removed, showing different forms of our improved joint.

Our invention has relation tothat. type of rail-joints wherein the splice-bars are provided with freely-depending flanges which extend below the rail-base, the object of our invention being to materially lighten the .middlemember or portion of the freely-depending flange, and thus cheapen the construction of the splice-bar, while at the same time providing increased resiliency; It has been demonstrated by practice t at under certain traflic conditions it is desirable to provide a joint having a preponderance of resiliency, and these conditions are designed to be met by our present invention.

With this object in view our invention consists in a splice-bar having a freely-depending flange to extend below the base of the ra l, said flange being of gradually-diminishing thickness toward its lower end. This flange may be of various specific forms, its

essential characteristic in every case bein the gradual diminution in thickness-towar its lower free edge. The lower ed e of the flange may be stiffened by a bea or rib, formed either at its inner or outer surface-or at both sides.

In the drawings the numeral 2 designates the splice-bar proper, which may be of the usual form, and 3- theflfreelydepending flan e. The freely dependin gra ually reduced 1n thickness om its upper to its lower edge. These flan es may be ent' outwardly or away from eac other, as shown in Figs. 1,2, and 3. They may be bent inwardly and downwardly, as shown in Figs. 5/6; 7, 8, 13, 14, 15, 1c, 17,- and 18. They may extend in substantially parallel vertical planes, as shown in Figs. 9, 10, 11,

and 12, or they may be bent horizontal] ina *ward underneath the base of the rai, as

the rai, sai

shown in Fig. 4. They may be of curvilinear form with either simple or compound curves,

as shown in Figs. 1, 2, 3, 5', 6,11, 12,13,1 1,

15, 16, 17, and 18, or they may be formed with a straight gradual taper, as in Figs. 4, 7, 8, 9, and 10. Any of the various forms illustrated may ormay not be provided with a stiffening bead or rib at its lower edge, severalforms of such beads being shown at 4 in Figs. 2, 5, 7, 10, 12, 14, 16', and 18.,

he precise form of the flanges in the several modifications illustrated will be bestunderstood'by reference to the drawings, and it will be obvious that various other modifications embodying the spirit of our invention may be made.

The advantages of our invention consist in the provision of a spliceebar having a freelydepending flange whose middle portion -or member is materially lightened, and which possesses a maximum of resiliency.

What we claim is"- 1. A splice-bar for rails having a freely-depending flange to extend below the base of the rail, said flange gradually decreasing in thickness toward its lower edge; substantially as described.

2. A splicebar for rails having a freely-depending flange to extend below the base of the rail, said flange gradually decreasin in thickness through its intermediate mi dle portion toward its lower edge; substantially as described. 1

' 3. A splice-bar for rails having a freely-depending flan e to extend below the base of the rail, sai creasing thickness toward its lower end, and stiffened at-its lower edge; substantially as described.

' 4. A splice-bar for rails having a freely-dependin' flan e to extend below the base of the rai, sai flange being of gradually-decreasin thickness through its middle portion and st' ened at its lower edge at the inner side; sub antially as described. I 1 5. A sp ice-bar for rails having a freely-dependin flan e to extend below the base of flange being of gradually-decreasin%thickness through its middle portion and sti side; substantially as described.

6 A splice-bar for rails having a freelyde-.

pending flange to extend below the base of flange being of gradually-deened at its lower edge at the outer Ice the rail, said flange being of gradually-decreasing thickness toward its lower edge and stiffened at its lower edge at both inner and outer sides; substantially asdescribed.

7. A splice-bar for rails having a freely-depending flange to extend below the base of described.

' 9. A splice-bar for rails having a freely-depending flange'to extend below the base of the rail, said flange being of gradually-decreasing thickness toward its lower edge and having a curvilinear face stiffened at or near its loweredge; substantially as described.

. 10. A splice-bar for rails having a freelydepending flange to extend below the base of the rail, said flange being of gradually-decreasing thickness through its middle portion .andstiffened at its lower edge uniformly upon both sides of its central plane; substantially as described.

11. A splice-bar for rails having a freelydepending flange to extend below the base of the rail, said flange having a reversely-curved middle portion or member which is of gradually-decreasing thickness toward the lower edge of the flange; substantially as described.

12. A splice-bar for rails having a freelydepending flange toextend below the base of the rail, said flange having a reversely-curved middle portion or member which is of gradually-decreasing thickness toward the lower edge of the flange, said flange being stiffened at its lower portion; substantially as described.

In testimony whereof we have hereunto set our hands. I
